       3. The image reading apparatus according to  claim 1 , wherein the apparatus body comprises a first unit that serves as a lower side of the reading transport path, and a second unit openable and closable with respect to the first unit, the second unit serving as an upper side of the reading transport path, wherein
 the position of the center of gravity of the apparatus body in the apparatus depth direction is, regardless of the state of the second unit, located at a position closer than the shaft axis to the apparatus front when the apparatus body is in the first position, and located at a position closer than the shaft axis to the apparatus rear when the apparatus body is in the second position. 
 
     
     
       4. The image reading apparatus according to  claim 3 , wherein the position of the center of gravity of the first unit is located at a position closer than the shaft axis to the apparatus rear in the apparatus depth direction when the apparatus body is in the second position. 
     
     
       5. The image reading apparatus according to  claim 3 , wherein the position of the center of gravity of the second unit is located at a position closer than the shaft axis to the apparatus front in the apparatus depth direction when the apparatus body is in the first position. 
     
     
       6. The image reading apparatus according to  claim 1 , wherein the apparatus body comprises a first unit that serves as a lower side of the reading transport path, a second unit openable and closable with respect to the first unit, the second unit serving as an upper side of the reading transport path, and a third unit rotatable with respect to both the first unit and the second unit, the third unit serving as a document transport path downstream of the reading transport path, wherein
 the position of the center of gravity of the apparatus body in the apparatus depth direction is, regardless of the state of the third unit, located at a position closer than the shaft axis to the apparatus front when the apparatus body is in the first position, and located at a position closer than the shaft axis to the apparatus rear when the apparatus body is in the second position. 
 
     
     
       7. The image reading apparatus according to  claim 1 , wherein the apparatus body comprises a weight that is located at a position closer than the shaft axis to the apparatus front in the apparatus depth direction when the apparatus body is in the first position and is located at a position closer than the shaft axis to the apparatus rear in the apparatus depth direction when the apparatus body is in the second position. 
     
     
       8. The image reading apparatus according to  claim 1 , further comprising:
 an operation section disposed on the front of the apparatus body in the apparatus depth direction, the operation section being configured to receive an operation from a user, wherein 
 the operation section is disposed at a position to rotate the apparatus body toward the first position when the operation section is pressed by the user, and 
 a distance between the position of the center of gravity of the apparatus body and the shaft axis in the apparatus depth direction when the apparatus body is in the second position is longer than a distance between the position of the center of gravity of the apparatus body and the shaft axis when the apparatus body is in the first position.
